1. Intonation of Greetings

27. The Gradually Descending Stepping Head. The High Head. The Broken Stepping Head.
St. Head.
Each fully stressed syllable beginning with the 2^nd lower in pitch than the preceding one. Unstressed and partially stressed syllables are said on the same pitch as the preceding fully stressed.
The GrDesSrepHead is sometimes called the most typical, or normal, kind of head in English. It is certainly the most frequently occurring single category jf head.
GrDesSrepHead is characteristic of only some kind of English: reading aloud, formal conversation, lecturing or some other kind of didactic monologue, although it may be heard in any other variety of spoken English.

High Head.

In the High Head all the syllables are said on the same rather high pitch. There is only one fully stressed syllable, ie one peak of prominence. This is the stressed syllable of the 1^st important word: the onset. The other semantic items in the prenuclear part are given a smaller degree of prominence indicated by a high partial stress.
When the head of an utterance contains only one notional word, ie it cannot be expanded, the difference between the Stepping and the High Head is neutralized.
The High Head is commonly used in conversation, where it occurs more frequently than the Stepping Head.
Sound: lovely, energetic, informal.

The Broken Descending Stepping Head.

The Gradually Desc St Head may have a monotonous effect especially when the intonation group contains more than three stressed syllables. The pattern is described in this case as the Broken Descending Stepping Head, and a tune containing such a head may be called A BROKEN TUNE.
The break generally occurs on any fully stressed syllable beginning with the third. The upward is usually made on words of sufficient semantic importance: nouns, adverbs, adj, verbs.
The syllable on which a special rise is made can be indicated in different ways:

1. 
   By a high static tone mark;
   
2. 
   By a straight upward arrow beside the high static tone;
   
3. 
   By an emphatic high static tone mark.
